Sakura bins


Recommended Posts

I don't quite understand the specification of these bins. It says 20-180x100, then states that the objective lens diameter is 70mm. At 180x, the exit pupil (for 70mm OB) will be less than 0.4mm. Not much light there!

I should steer well clear of them!

Indeed

A guy sells these at a local a local car boot every week and I have inspected and looked through them.

They are almost unusable in daylight !

An old pair of 10x50's from the charity shop for £10.00 is a much better investment and use of your money.

Plus you can try them out.
